CLEVIS.

SPECIFICATION forming part of Letters Patent No. 343,474, dated June 8,1886.

Application filed May 5, 1886. Serial No. 201,209. (No model.)

- part of this specification.

This invention relates to a clevis the hook of which is adapted to beadjusted so as to regulate the cut of the plow and cause the same to rundeep or shallow, as the nature of the soil or work may require.

On the drawings, Figure l is a perspective view of a stirrup-shapedmetal strap and pin for securing same to the forward end of a plow beamor pole. Fig. 2 is a similar view of a coupling-hook adapted to connectwith the aforesaid strap. Fig. 3 is a vertical longitudinal section ofthe clevis as when connected with a plow beam or pole; and Fig. 4 is aview from the inner ends of the strap.

The letter A designates a stirrup-shaped metallic strap, which isadapted to snugly fit over the forward end of a beam or pole, B, towhich it is designed to be secured by a pin, C, that is inserted inholes made to receive the same in both ends of the strap and in the beamor pole embraced thereby, as shown at a n1 rig. a

ToV prevent the accidental displacement of the aforesaid pin by thejarring or rough handling of the implement, the lower end of the pin isprovided with a screw-thread and nut, or in lieu of a nut, the hole inthe lower side of the strap may be tapped to receive the aforesaid endof the pin, as shown at d in Fig. 3.

the aforesaid circular holes, in order that when the strap is loosenedfrom the beam the said hook can be moved from one hole to the other bysimply sliding the hook inwardly until its flattened portion is broughtinto line with the slit,when it can be readily moved through the same inthe direction desired.

From the above description it will be seen that my invention not onlypossesses the advantage of a swivel-hook, but that the said hook may beelevated or lowered, as desired, and thus aord means for either acentral or an upper or lower pull, as required. The hook is readilychanged from the lower to the upper hole, or vice versa, by simplyloosening the strap and moving it sufficiently to allow the hook to beslipped inwardly and then upwardly or downwardly, as the case may be.

Vhen all the parts are joined together, the shank and head of the hookis held in either of the countersunk holes by reason of the end of thebeam abutting against the same, asis clearly shown in Fig. 3.

When it is desired to pull from the center of the beam, the hook shouldbe turned-inwardly, which will bring its forward portion in proper line,whether the shank thereof bea resting in the upper or lower hole of thestrap. For a deep cut the hook should be placed as shown in full linesat Fig. 3, and for a shallow cut as shown in dotted lines in sameligure.

Having described my invention, what 4I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in a clevis, of astirrupshaped strap having itselosedend provided with upper and lower holes and a slit connecting thesame, as described, with a hook having a flattened and a roundedportion, whereby it is adapted to be moved in the aforesaid slit orswiveled in either of theholes connected thereby, substantially as andfor the purpose set forth.

2. The combination of a stirrup-shaped strap having its closed endprovided with countersunk holes and a slit connecting the same, asdescribed, a flattened hook having a round shank and conical headadapted to oproo crate in the aforesaid holes and slit, and :i piu Intestimony whereof I aix my si gnature in whereby the strap is secured to:1. plow beam presence of two witnesses. or pole, so that the end of thelatter shall T T abut; against the head of the hook and thus IUCHARDSOBMONTFORT' 5 hold the same in the socket within which it is Vitnesses:
